Lifegard Aquatics Digital Temperature Alert Aquarium Light for Accurate Monitoring

Neftali Acuna: It is pretty accurate and the long cord makes it easy to put it in the tank or bathtub, however, I would like to see it with more weight at the end of the sensor, so that can go down the water and not to float back up.

R. Boyd: This product has no temperature alarms. It is hard to tell this from the description. The only alarm is associated with the clock: it has an alarm clock function, which is useless on this product. On the other hand, the temperature display is very big and appears to be pretty accurate (matches other thermometers that I have to within one degree F).
The clock function loses time pretty fast - it loses about 1/2 hour per week!! You cannot rely upon the displayed time, which fortunately is not nearly as large as the temp displays.
Bottom line: this is a pretty good thermometer - but that is all it is. It is not a temp alarm and the clock is useless.

Kindle Customer: Directions that come with suck. Otherwise it's great. You just have to play with buttons until you figure it out on your own.

Paulb: It's just a dual thermometer (probe, and body). Has a clock and an alarm clock function. Remembers max and minimum temperature. Does NOT have a temperature alarm as the description indicates. Grossly incorrect most of the time.

Roberto: El termómetro con alarma de alta y baja temperatura funciona a la perfección. Hice pruebas aumentando y bajando la temperatura por arriba y por debajo de los límites que establecí activándose la alarma de inmediato en ambos casos. Altamente recomendable.

Goodies2go: This is my second one. Wish they were more water proof. If you accidentally drop it in water, for even a quick second, it may or may not revive upon drying out. Aside from that, I really like this model. It lasts, if you keep it dry, and has good reliable function. The alarm helps, occasionally in the summer my little pond can get hot and this let's me know to add ice to cool it down a degree or so.

BREAVIELL: An amazing product! I currently use no less than 14 different thermometer models and types for various aquaria. This is by far the most accurate (when compared against standard mercury units). I'd say it's accuracy is within a .01F variance, which is unheard of in this marketplace. It's also built very well - quite sturdy. The large readouts are a huge plus. The alert warning feature works precisely as intended. in fact, it has already been responsible for saving one of my bettas when the heater stopped working. The alert signal is loud enough, too, that I can hear it in almost every corner of the home. The only 'negative' I have would be that the sensor cord is a little too short, meaning you are pretty well forced to install the monitor right at your tank with no leverage to place it even a short distance away from the tank. But hey, that's nothing compared to the overall excellence of every other feature of this product. All that said, I am very familiar with the fact that when it comes to aquarium thermometers, not all are created equal -- even if its the same model. For some reason, these products are quite finicky and you pretty much have to get...

McGadget: Good product. Nice size and easy to see even when lights are out just from the glow of the aquarium lights. I placed it on a wall next to the aquarium. It does come with a bracket for the wall and a built in stand. Overall I am pleased with the product. Instructions are poor but it easy to figure out on your own.

Would be better if it had a lightly backlit blue background with a wired power source. Also would be better if one could have centigrade/celcius option in addition to just Farenheit.
